As shown in fig. 1, the present embodiment provides an operating system of a modular ozone generator, which includes a plurality of power-discharge chamber groups 100 connected in parallel, a power supply 10, a water path pipeline 20, a gas path pipeline 30 and an ozone pipeline 40, wherein the power supply 10 provides a main power supply for the power-discharge chamber groups, cooling water flows through the water path pipeline 20, air or oxygen flows through the gas path pipeline 30, and ozone generated by the power-discharge chamber groups 10 is output through the ozone pipeline 40.
Specifically, in the present embodiment, as shown in fig. 1, each power supply-discharge chamber group 100 includes a power supply module 110 and a discharge chamber module 120 connected in series, respectively, wherein each power supply-discharge chamber group 100 is further connected in series with an operation state monitoring system, the power supply module 110 can provide a high voltage power supply for the discharge chamber module 120, air or oxygen in the air path pipeline 30 can enter the discharge chamber module 120, ozone is generated by the high voltage power in the discharge chamber module 120, and finally ozone is discharged and collected through the ozone pipeline 40. The running state monitoring system is electrically connected with the single chip microcomputer and can monitor the running state of the power supply-discharge chamber group. The single chip microcomputer receives signals of the operation state monitoring system, so that the operation state of the power supply-discharge chamber group is judged. If the operation condition of the power supply-discharge chamber group is damaged, the single chip microcomputer can transmit a signal to the operation state monitoring system, so that the power supply-discharge chamber group stops working.
Specifically, in the present embodiment, the operation state monitoring system includes a control module 131 and a high voltage detection module 132. The control module 131 is configured to control on/off of a circuit of the power supply-discharge chamber group, and the control module 131 can receive a signal sent by the single chip microcomputer. As shown in fig. 2 and fig. 4, the CTRL0 terminal in fig. 2 is a control output terminal of the single chip, which is connected to the control module circuit in fig. 4. Preferably, in this embodiment, as shown in fig. 4, the control module 131 includes an optical coupling module and a relay connected in series, where the optical coupling module controls the closing of the relay, and the relay is connected to the input end of the power supply module. When the single chip microcomputer receives the signal sent by the high voltage detection module 132, the single chip microcomputer sends a control signal CTRLi (i is the number of the circuit, for example, CTRL1, i.e., circuit No. 1) to the control module 131, and the relay K11 is controlled to be closed by the optocoupler module, so that the power supply module 131 is powered off, and the entire power supply-discharge chamber assembly 100 is in a powered off state. In addition, after the single chip microcomputer sends out a control signal, the control signal can drive an indicator lamp (an XLED output end in fig. 2) to be turned on, so that an operator can determine the operation state of the discharge chamber module 132 according to the display of the indicator lamp. In addition, a first photoelectric isolation module can also be connected in series in the control module 131, so that the circuit of the whole control module is stable in operation, and the anti-interference performance of the whole control system is improved.
In this embodiment, the high voltage detection module 131 is used to determine whether the voltage in the discharge chamber module is normal, and if the high voltage detection module 131 determines that the voltage in the discharge chamber module 132 is abnormal, the high voltage detection module 131 sends a signal to the single chip microcomputer. As shown in fig. 2, the CHKi (i is the number of the circuit, for example, CHK1, i.e., circuit No. 1) end of the single chip is connected to the high voltage detection module 131 in fig. 3. Preferably, as shown in fig. 3, the high voltage detection module 131 includes a sampling resistor Ri (i is the number of the circuit, for example, R1, i.e., the sampling resistor R in circuit No. 1), a comparator module, and a second optoelectronic isolation module. As shown in fig. 3, a sampling resistor Ri is connected in series before the discharge chamber Ci is grounded, a voltage across the sampling resistor Ri is transmitted to one end of the comparator module, a set voltage (input by an operator) is preset in the comparator module, the comparator module compares the voltage across the sampling resistor Ri with the set voltage, the comparator module controls the U _ GD of the second optoelectronic isolation to be turned on or off according to a comparison result, if the voltage across the sampling resistor Ri is higher than the set voltage, the U _ GD of the second optoelectronic isolation module is controlled to be in an on state, and if the voltage across the sampling resistor Ri is lower than the set voltage, the U _ GD of the second optoelectronic isolation is controlled to be turned off. When the discharge chamber is normal, the sampling voltage is higher than the preset comparison voltage. The single chip microcomputer judges the state of the discharge chamber according to the judgment result of the high-voltage detection module 132, so that whether the control module is turned off or not is controlled. If the second photoelectric isolation module is in a conducting state, the single chip microcomputer judges that the discharge chamber module works normally, so that the control module is in a conducting state; if the second optoelectronic isolation module is in an off state, the single chip microcomputer determines that the discharge chamber module works abnormally, and the single chip microcomputer sends a signal to the control module 131, so that a relay in the control module 131 is turned off, and the discharge chamber module is protected.
The power module, the discharge chamber module, the high-voltage detection module, the control module and the like are subjected to modularized structural improvement, local control is achieved, and the defect that the existing integral binding structure is damaged locally and affects the whole body is avoided. In addition, in the huge cascade system of the embodiment, the discharge chamber module of the embodiment is only locally stopped after being locally damaged, and the whole ozone generator system can still be used in a short-time derating way, so that the whole cascade system is not totally paralyzed. Maintenance personnel can change each module assembly (the module cuts off the power supply, closes the aqueous vapor pipeline valve, changes discharge chamber module or power module) under the condition of not shutting down the operation, after the maintenance finishes, resumes normal operation of putting into operation again.
In this embodiment, no matter whether the MCU singlechip of MCS51 series or the STM32 embedded MCU singlechip uses assembly language or C language, the control idea is similar. The methods according to the present application are all conveniently implemented.
It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
